Abstract 2238: Targeting Cognitive Impairment in Heart Failure with a Memory Intervention
Background: Cognitive impairment has been reported up to 1.96 times greater in people with chronic heart failure and may affect patient outcomes by impairing the ability to integrate new information needed for self care. Problems with concentration, memory, and attention have been reported. The effects of memory training strategies on this population are unknown.
Method: Comprehensive strategies aimed at improving cognitive impairment and everyday memory were incorporated into the education modules and teaching sessions used during a three-month in-home education-support intervention. Pre and post-test measures using two subscales (Change and Capacity) of the Metamemory in Adulthood Questionnaire (MIA) were obtained from 34 participants in a randomized control study at T1 baseline and T2 after the intervention. Participants were 45 years and older, Class I–III HF, and randomized to the intervention (N=20) or an attention-control group (N=14). Means, standard deviations, Wilcoxon Signed Ranks Tests, and Mann-Whitney U tests were calculated to compare the groups.
Results: The Capacity subscale measures the perception of memory capacities by rating performance on given tasks. The intervention group showed significant improvement in the Capacity subscale compared to the control group–Intervention group (n= 20) mean scores T1= 51.70 (SD+/− 11.66), T2= 56.40 (SD+/− 9.21), Z= −2.14, p= .033; Control group (n= 14) mean scores T1= 59.71 (SD +/− 9.82), T2= 56.90 (SD+/− 10.24), Z= −1.42, p= .157. The Change subscale measures the perception of memory abilities as generally stable or subject to long-term decline. Significant improvement in the Change subscale was found in the intervention group compared to the control group–Intervention (n=20) mean scores T1= 43.81 (SD/−14.42), T2= 50.21 (SD+/− 14.06) Z= −2.65, p= .008; Control (n=14) mean scores T1= 54.30 (SD+/− 13.04), T2= 52.46 (SD+/− 10.52), Z= −.88, p= .379.
Conclusion: The intervention group had significant improvement on the memory Capacity and Change subscales of the MIA following a targeted intervention. There was no improvement found in the control group. Memory training may be a useful component of future interventions for cognitive impairment in people with heart failure.
